Application Case

HPLC method configuration for preservatives and sweeteners in wine

A wine testing workflow used LC500 HPLC, SPD-500 UV detection, manual injection, workstation support, and a C18 column to measure benzoic acid, sorbic acid, acesulfame potassium, and saccharin sodium according to the GB/T 23495-2009 reference method.

Background

Requirement context

The method content from Tianzhao's China site describes a preservative and sweetener test for wine. The application is useful for overseas buyers because it connects the analyte list, reference method, detector, column, and HPLC configuration before quotation.

Selection challenges

What needed confirmation

Confirm the target analytes before selecting detector wavelength, column, and workstation scope.

Match the method to a C18 column and UV detection workflow.

Prepare an RFQ that separates the HPLC system, UV detector, injector, workstation, and column requirements.

Workflow architecture

From requirement to quotation

Instruments

LC500 HPLC system, SPD-500 UV detector, manual injection valve, workstation, and C18 column.

Confirmation Layer

Method requirements covering analytes, reference method, wavelength, column, and data review.

RFQ Review

Food testing RFQ built around complete HPLC method configuration.

Configuration path

Application stages

Separation system

LC500 HPLC with C18 column

Separate wine preservatives and sweeteners before UV detection.

Detection and data review

SPD-500 UV detector, manual injector, and chromatography workstation

Measure benzoic acid, sorbic acid, acesulfame potassium, and saccharin sodium.

Result

RFQ output and buyer value

Reference method

GB/T 23495-2009 was used as the method reference.

The RFQ can be organized around a known food testing method instead of a generic HPLC request.

Method configuration

LC500 HPLC, SPD-500 UV detector, C18 column, injector, and workstation were identified as key components.

The buyer can confirm all method-critical modules before pricing.

The method strengthens Tianzhao's food and beverage testing application coverage.

The case creates a practical cross-link between HPLC systems, UV detectors, and C18 columns.

The application is suitable for food testing laboratories that need preservative and sweetener analysis.
